What Serinex does

Serinex is an Italian precision mechanics company, founded in 1989 and organized as SE.RI.NEX S.r.l., that designs and manufactures toolholder components including elastic collets, pull studs, clamping nuts, toolholders, and accessories. The company operates an in-house production platform comprising three CNC-equipped departments (turning, milling, grinding) inside a 7,000+ sqm facility in Annone Brianza, producing from certified alloy steels with ultrasonic quality control and a proprietary superfinish surface treatment that achieves surface roughness below Rz 2.5. Its 6,000+ SKU catalog is offered across three rotation-accuracy classes (Standard 0.015mm, Ultra Precision 0.005mm, Mega Precision 0.002mm) and covers major international toolholder interfaces including HSK-DIN69893, ISO26623-1 Capto, BT-MAS403, DIN, and cylindrical spindles. The company holds ISO 9001:2015 certification, continuously since 1998, and sells primarily to metalworking, medical equipment manufacturing, woodworking, marble/stone processing, and CNC machine OEM customers.

The business model combines B2B e-commerce (shop.serinex.it, powered by WooCommerce with Stripe payment processing) offering customized pricing, real-time availability, order tracking, and multi-user account management, with direct enterprise field sales for OEM and custom-design accounts. Revenue is generated from hardware sales of standard catalog components, custom design and engineering services for special toolholders from customer drawings, private label / third-party production, and value-added services including dynamic balancing with dimensional certification, shrink-fit assembly, and scheduled stock management with planned deliveries for large-volume buyers. Distribution is global via the e-commerce platform with an explicit focus on European industrial buyers.

Serinex is privately held by founders Piermario Negri and Serafino Riva, with no disclosed venture capital, private equity, or institutional investment, and issued share capital of €10,400 indicating a family/founder-owned small-to-medium enterprise. Marketing is conducted primarily through trade exhibitions (e.g., Tornitura Show 2023), the multi-language corporate website, organic social channels, and ESG-oriented communications including a planned 2023 photovoltaic installation and FSC-certified packaging.
